There is a growing problem with plastic waste in our oceans.

And what happens if they become a protected species. A food source will have to be provided, lest they die out. =============================== To unsubscribe from this mailing list, send the message: unsubscribe (in the body of the message, with no Subject line) http://birding-aus.org ===============================
Ah…the irony that the bugs have colonised something made out of the product that comes from the dead bodies of their ancient ancestors.

I have a similar thought to Christine. Most microbes are denser than seawater, so sink to the lower ocean depths unless they are brought to, or close to, the ocean surface by water currents. Floating plastic could provide a substrate for colonies of microbes that would otherwise sink more readily to the lower ocean depths as soon as they are not being influenced by those ocean currents.

Plastic bags and bins filled with water tend to sink I believe. I have seen plastic items on the substrate of Sydney Harbour. Chris Christine Melrose 0407705140 cmelrose099@gmail.com float. plastic waste is not sinking to the ocean floor. It is not accurate to say there is no increase without quantifying plastic debris within different substrates of the ocean body in different locations and within different periods of time. wrote: interesting slant to the problem. =============================== To unsubscribe from this mailing list, send the message: unsubscribe (in the body of the message, with no Subject line) http://birding-aus.org =============================== =============================== To unsubscribe from this mailing list, send the message: unsubscribe (in the body of the message, with no Subject line) http://birding-aus.org ===============================

The density of plastic and physics should tell you what items sink and float.

A very interesting article indeed. How do they know, however, that the plastic waste is not sinking to the ocean floor. It is not accurate to say there is no increase without quantifying plastic debris within different substrates of the ocean body in different locations and within different periods of time.
